Rosie Huntington-Whiteley has revealed she's been advised to have botox - at the age of 24.

The model, who this month was named the world's sexiest woman in FHM magazine, makes her film debut in the next instalment of the blockbusting Transformers franchise and says there is pressure to look a certain way in Hollywood.

In an exclusive interview with UK Elle magazine, she said a dermatologist had advised her to have the anti-wrinkle treatment.

She said: "Recently, I had a dermatologist tell me to try Botox. I'm 24! I just laughed. You can really get carried away if you want to - it's important to see beyond the bulls***.

"I'm not going to change my teeth or get a nose job. That manufactured perfection does nothing for me."

The model added that she knows expectations are not high for her performance as Shia LaBeouf's new sidekick in Transformers: The Dark Side Of The Moon, which is out on July 1.

She said: "I realise what people think. But that can't affect my life or my choices.

"I haven't claimed to be an amazing actress. I want to work, that's all. I want to pay my bills and make my family proud. I've got no other criteria apart from that."

Rosie replaced Megan Fox in the franchise after she had a public row with director Michael Bay.
